Yeah, and I think I have found the problem....looks like it was just a blown headgasket.....and its in the corner where that one grey exhuast valve was.... I'm pulling the old motor out tomorrow and I'll get some pics and post them up and see what you guys think....

Thats what mine started doing Nem....it wasn't running hot at all, but over a week it would drink all the coolant in the overflow bottle.....it did that for about 2 months, and then sh!t itself the other week......I'm about to reinstall my condensor in front of the radiator, and move the fan to...

Found it, 2003+ models but....see this link. http://www.top4runners.com/ja/runhist4.html The Land Cruiser's 4.7-liter dohc I-Force V8, 235hp 320 lb torque, is a first time 4Runner option. Debuting in the Tundra pickup in 2000, the iForce V8 has gained a reputation as one of the smoothest...

Wasn't there a 3rd or 4th Gen 4runner that had a V8? not sure if it was from the UZ family but....

Well my V8 sh!t itself a couple weeks ago, which most likely started from when I cooked it late last year when the thermo fan blew a fuse while towing my zook out to Landcruiser Park. Anyway, I picked up a new V8 this week from Scott at Venom and will be putting it in this weekend....I ran some...

Nice job on the conversion Max!!! Got any pics of you whole truck? And who did you exhaust headers? I need a set for my 4runner, but didn't think they'd be able to fit in the space I've got....but yours seem to fit perfectly!!

The cams were easy to get out.....there was a little tention on them when loosing the clamps that hold them down onto the valve springs, but they don't bounce off or anything when you undo them.... Priced getting the heads checked out, the cheapest I got was $210 to just pressure and crack...

Yeah Jibby, am running the stock cams...Low end torque is fine for the offroading I do in it (its more than what I had though the whole rev range with the old motor), but the engine braking for steep descents isn't as good as the old V6.

The engine bay with the heads off... I guess this is why it misses a bit at idle? See how the top left valve is grey, while all the others are pink? anyone know why this would be? The other head.......

Yeah found out we had to remove the cams to get the heads off when we got to that part....what you's had all said made sense then..... Anyway, we got the heads off, which wasn't too bad a job, but I still wouldn't like to have to do it again, and am not looking forward to putting it back...

Might as well tell you's the whole story too.......I didn't run coolant for 12 months :bigeyes: (yeah I know)....The radiator we first used was just to get the engine complianced....my new radiator was supposed to be done 2-3 months later.....but my mate kept dragging it out, then soon enough 12...

Ok then....I'm a little lost......I wasn't planning on touching any of that....well kinda not anyway.... I need to replace the headgaskets, and was just going to pay someone to check out the heads for me while they are off, and get them to do what they do.... I got a full genuine VRS kit...

Hey All, Am halfway thorugh pulling the motor to bits to get the heads off....Just got to pull the timing belt stuff off, intake manifold, and cam covers, and they should be right to come off. I'll be pulling them tonight, but I just thought I'd check if there is any special tools...

Hey Guts what ended up happening with this??? The 4runner started having all the exact same symtoms yesterday...:damnit: The missus will take it into work early next week and get a compression test done, but I've got the same predeciment with wether to fix this motor, or buy another motor...

There is a Bundera with a 1UZ in it for sale on the 4WD Monthly Forum....don't know any details but heres a link to the thread. http://www.4wdmonthly.com.au/forum/index.php?board=12;action=display;threadid=15151

My mate is a panel beater and did them for me after he resprayed some other bits of the 4runner. He just used the same paint that was used on the car, but had to to prep it with some kind of aluminium cleaner (sorry not sure on the details) which cost about $50 Au..... I was stoked with how...

Nah, deffinetly blew the diff...the crown wheel had about half its teeth missing......Luckily they are a cheap diff, easily available.....only cost $150 for another one.........would love to go SAS in the future but!!

Cool pic Guts!!! I'll deffinetly keep an eye out for the Issue!!! Whens your first comp with the Lexus?

Sorry for using this thread as a test, but just seeing if mine works.....doesn't seem to update old post with the new signature...?? Edit: Sweet it works!!! If it gives people the sh!ts let me know and I'll remove it....

My 1UZ doesn't run the the coolant through the throttle body, or the ISCV, then were removed when I picked my motor up from Venom...Scott said they weren't needed unless you live in the snow.... But mine does do the same as the symtoms in this thread (high cold start idle and running rough at...
